Boggs Eumorphic

Interrupted Boggs Eumorphic

This example shows a world map using the interrupted Boggs eumorphic projection, a composite of the sinusoidal and Mollweide projections. The map displays landmasses, country boundaries, and graticules, with the projection interrupted into separate lobes for the northern and southern hemispheres. The code uses `d3.geo.interrupt` with `d3.geo.boggs.raw` from the geo.projection plugin, along with `d3.geo.path` for rendering SVG paths. It loads world-50m.json via TopoJSON and clips all features to a spherical outline using a clipPath.

Mollweide

This example shows a world map projected using the Mollweide projection, with graticule lines, land masses in dark fill, and country boundaries in white. The map is rendered as SVG using D3 v3 with the `d3.geo.mollweide` projection, `d3.geo.path`, and `d3.geo.graticule`. Land and boundary data come from a TopoJSON file of world countries, processed with `topojson.feature` and `topojson.mesh`. The code defines sphere, stroke, fill, graticule, land, and boundary CSS classes to style the visual layers.

Mollweide Hemispheres

This example displays a world map using the Mollweide projection, interrupted into two hemispheres—northern and southern—which are rotated twenty degrees and centered on a 960-by-500 SVG canvas. The map shows landmasses as dark shapes with white country boundaries, overlaid on a graticule, all clipped to a circular sphere. It uses the `d3.geo.interrupt` and `d3.geo.mollweide.raw` projections with `d3.geo.path`, and renders geographic data from a World 50m TopoJSON dataset, drawing both land polygons and a mesh of country boundaries.

Eckert V

This example displays a world map on the Eckert V projection, rendered in SVG for a 960-by-500 viewport. It uses the `d3.geo.eckert5` projection from the geo.projection plugin and `d3.geo.path` to draw graticules, landmasses from a TopoJSON world-50m file, and country boundaries derived via `topojson.mesh`. The map is styled with contrasting strokes and fills against a light background.

Eckert VI

This example demonstrates the Eckert VI map projection, a pseudocylindrical equal-area projection that displays the entire globe within an ellipse. The map shows world land masses as dark regions with white country boundaries overlaid on a graticule, all rendered as SVG. The code uses the D3 v3 library with the `d3.geo.eckert6` projection plugin, `d3.geo.path` for projecting geographic features, and `d3.geo.graticule` for the coordinate grid. World data comes from a 50m resolution GeoJSON file loaded via `d3.json`, and TopoJSON is used to extract land and boundary shapes.

August Projection

This example displays a world map using the August projection, a pseudocylindrical equal-area projection that curves parallels and meridians into distinctive intertwined shapes. The map renders land masses in dark gray with white country boundaries overlaid on a graticule, all enclosed within a spherical outline. Using D3 v3, the code employs `d3.geo.august` for the projection, `d3.geo.path` to draw geographic features, and `d3.geo.graticule` for the grid. TopoJSON data provides the world land and country boundaries, loaded from an external JSON file.

Eckert I

This example displays a world map using the Eckert I projection, with landmasses filled in dark gray and country boundaries outlined in white against a graticule grid. The spherical outline is drawn with a thick black stroke and white fill, emphasizing the projection’s oval shape. The visualization uses D3 v3, the `d3.geo.eckert1` projection from the geo.projection plugin, and `d3.geo.path` to render geographic features. World data comes from a TopoJSON file (`world-50m.json`), processed with `topojson.feature` and `topojson.mesh` to separate land and country boundaries.

Eckert III

This example demonstrates the Eckert III map projection, a pseudocylindrical projection that preserves equal area. The SVG canvas displays a graticule and world map, with landmasses rendered in dark gray and country boundaries in white. Using the D3 v3 library, the code employs `d3.geo.eckert3()` for the projection, `d3.geo.path()` to draw geographic paths, and `d3.geo.graticule()` to generate the grid. The world map data is loaded from a remote GeoJSON file via `d3.json()` and transformed using the TopoJSON library.
